I have an aluminum intake manifold that appears to be NOS. It is a V8 Chevrolet manifold with the part # 14044836 on it. I have heard rumor that these are from a 69-70 Z28. Is there any truth to that? I have searched all over for information on this manifold and it's specs, but I keep coming up empty handed. Any information would be appreciated; especially a point in the right direction for verification of specs or application. Thanks! Sal
